Determining Which Messages to Sign, Encrypt, or Sign and Encrypt
After you create a sending profile, you need to create an outgoing content filter that determines which 
email messages should be signed, encrypted, or signed and encrypted. The content filter scans outgoing 
email and determines if the message matches the conditions specified. Once the content filter determines 
a message matches the condition, the Email Security appliance signs, encrypts, or signs or encrypts the 
message.
